Saving Behavior

There was a blackout in early August 2019, forcing everyone to think about electricity. Some expressed the need for management reform, use of new renewable energy, and promoting energy-saving behavior. However, energy saving behavior without good knowledge will make it difficult to carry out the behavior. For this reason, the community service team collected data through a questionnaire to determine the energy saving knowledge of lighting for students. Furthermore, there is provision on energy saving lighting and practice in the field to determine the extent to which energy saving is implemented in the study room. This practice is in the form of measuring the light intensity of the study room, to find out its value so that if it is not enough, it is necessary to take action to comply with SNI standards. The presentation of the lighting field briefing contained, among other things, the explanation that saving energy does not mean reducing the use of electric power alone, but rather that saving energy must maintain the quality of lighting. Based on the results of the pre test, students have a high desire to behave energy-saving by 91.3% and have confidence in the results of a behavior and an evaluation of the results of a high behavior is 99.5%. The study room illumination shows a value that is not in accordance with the SNI, which is between 125 Lux to 150 Lux. This value is far from the SNI standard, which is 350 Lux for classrooms. Based on the results of the application of this SNI, then the lighting design is carried out through simulation using the Dialux software and the installation of energy-saving lamps in the study room, so that it reaches the SNI standard.ABSTRAK:Terjadinya pemadaman listrik pada awal Agustus 2019, memaksa semua orang untuk berpikir tentang kelistrikan. Sebagian menyatakan perlunya pembenahan manajemen, perlunya pengelolaan/penggantian sistem, dan usulan penggunaan energi baru terbarukan. Selain itu masih terdapat hal lain, yaitu peningkatan perilaku hemat energi (HE), antara lain berupa peningkatan pengetahuan HE. Namun HE kadang-kadang diartikan lain, yaitu hanya sekedar mematikan lampu, tanpa memperhatikan kualitas visual. Untuk itu tim pengabdian kepada masyarakat ini melakukan pengambilan data melalui kuisioner untuk mengetahui pengetahuan HE kepada siswa SMA N 23 Jakarta. Selanjutnya dilakukan pembekalan mengenai HE dan praktik di lapangan untuk mengetahui sejauh mana pelaksanaan HE yang ada sekolah tersebut. Praktik ini antara lain berupa pengukuran intensitas cahaya ruang belajar, untuk mengetahui nilainya sehingga jika kurang perlu dilakukan tindakan untuk disesuaikan dengan standar SNI. Penyampaian pembekalan bidang pencahayaan, antara lain berisi tentang penjelasan bahwa HE bukan berarti mengurangi penggunaan daya listrik saja, tapi lebih diutamakan bahwa HE harus tetap menjaga kualitas pencahayaan. Berdasarkan hasil pre test, siswa memiliki keinginan tinggi untuk berperilaku hemat energi sebesar 91,3% dan memiliki keyakinan akan hasil dari suatu perilaku dan evaluasi terhadap hasil perilaku yang tinggi sebesar 99,5% Tingkat pencahayaan/Iluminansi ruang belajar menunjukkan nilai yang kurang sesuai dengan SNI, yaitu antara 125 Lux sampai dengan 150 Lux. Nilai ini jauh dari standar SNI, yaitu 350 Lux untuk ruang kelas. Berdasarkan hasil penerapan SNI ini, selanjutnya dilakukan perancangan pencahayaan melalui simulasi dengan menggunakan perangkat lunak Dialux dan pemasangan lampu HE pada ruang belajar tersebut, sedemikian sampai mencapai standar SNI.

Saving Behavior

The pro-ecological and pro-saving behavior of households as energy consumersThe aim of the article is to indicate the changes related to households’ behavior linked to energy saving and pro-ecological activities. Therefore, the authors conducted acomparison analysis of the results of the nationwide Polish research about Polish ecological awareness and identified — as part of the Polish National Science Centre NCN project called “Modelling prosumers’ behavior on theenergy market” — pro-economical attitudes of households. The first part of this paper pre­sents the opinions of Poles about the possibilities of development of the different kinds of energy sources in Poland, taking into special consideration the development of renewable energy sources. In the second part of this paper the authors describe households’ behavior connected with saving energy. They analyzed pro-economical behavior such as: switching off lights in empty rooms, un­plugging phone chargers after use, using economical bulbs and unplugging devices that are not in use. The diversifying variables of behavior are: sex, age, income. The analysis of households’ behav­ior was supplemented with the analysis of pro-economical attitudes of Wroclaw university students.

Local Opposition

Renewable energy (RE) sources are often locally available and have the potential to lessen the rural dependence on the national power grid, reducing disruptions in power supplies and the heavy dependence on coal combustion. Poland faces an EU mandate of a 15% share of renewables in energy generation by 2020. However, the installations intended to supply several types of RE encountered local opposition, forcing a cancellation of the planned investments and stressing a need for understanding rural residents’ attitudes towards RE in general. Using survey data, this paper examines the perception of RE importance among rural residents in eastern Poland. The specified empirical relationship includes the sociodemographic and economic characteristics of residents. Perceptions of the links between health and specific sources of environmental pollution and actions demonstrating energy-saving behavior serve as explanatory variables. The performance of the estimated logit equation was rigorously tested. The probability of attaching importance to RE by rural residents increases most if a respondent displayed an energy-saving behavior, has certain demographic characteristics, and links health to environmental pollution caused by coal combustion. The graphic depiction of the effects of selected variables succinctly communicates possible future programs aimed at strengthening the rural population support of RE.

Global Energy Consumption

According to United Nations data, half of the world’s population lives in cities and forecasts indicate that by the middle of the 21st century, this percentage will have increased to 65%. The increase in the urban population favors the creation of a network of interactions that entails a series of material and energy flows. These cause environmental impacts that affect the quality of life of citizens and the environment as a whole. According to data from the International Energy Agency, cities occupy 3% of the planet’s surface and are responsible for 67% of global energy consumption. The effects caused by this consumption, as well as its impact on the depletion of resources, make it necessary to carry out an exhaustive study of renewable energies and new energy saving systems. This Special Issue aims to present new advances and developments in renewable energy and energy saving systems that allow cities to evolve in a sustainable way.

Behavioral Reasoning

With the increasing public’s energy consumption, the resident’s energy-saving behavior has been paid more attention by all walks of life. Therefore, it is important to find out what factors influence the public's energy-saving behavior. The paper constructs a conceptual model of Chinese rural residents' energy-saving behavior of habit adjustment based on behavioral reasoning theory. It examines the energy-saving behavior of habit adjustment of rural residents on the basis of investigation data from rural residents in China. We reach the following conclusions: environment values not only significantly influence global motives (including attitudes about saving energy, subjective norms, perceived behavioral control) but also via the reasons for behavior have indirectly influences to it, thereby influencing rural residents' energy-saving intentions. The reasons for behavior have an indirect impact on rural residents' energy-saving intentions via the global motives. The reasons for behavior also directly influence the rural residents' energy-saving intentions. The attitudes about saving energy, the subjective norms and the perceived behavioral control have indirectly positive impacts on rural residents' energy-saving behavior of habit adjustment via the energy-saving intentions. The Poyang Lake Ecological Zone has an important ecological protection function in China. Promoting rural residents in there to save energy can effectively protect the environment.

One of the common strategies used to minimize the spread of Covid-19 is to wear a cloth mask. Cloth masks have a lower effectiveness value compared to other types of masks but have the potential to be used as an alternative, especially during a pandemic. Smartphone can be used as an initial idea for determining the quality of a cloth mask. In taking pore images, there are factors that have the potential to affect the results of pore size, namely distance, angle of inclination, and light intensity. Taking photos of masks with a magnification application is done with three variations, namely distance, angle, and light intensity. The distance for taking pore images is varied to 3, namely 8 cm; 10 cm; and 12 cm. The image capture angle is varied to 0p; 5o; and 10o. measurement using a distance of 10 cm has the closest value from the measurement results by taking images using a microscope, which is 0.232 mm. In the variation of the angle, the angle that is parallel or 0o to the plane of the cloth mask has a value that is close to the microscope measurement, which is 0.232 mm. The light intensity measured using a lux meter which shows the results of 240 has a value that is closest to taking an image using a microscope, which is 0.221 mm.
